How Does Stepper Motor Works – Part 2
BY: SC Lim, RH2T Mag, Volume 3, Dec 09 Part 1 covered the characteristic, ratings and specifications, fundamentals of operation, and different types of stepper motor. This time, we’ll cover the drive methods. Topic Review Stepper motor is a rotational positioning actuator designed to produce motion in “steps” (basically 200 mechanical positions …
How does Stepper Motor Works – Part 1
By SC Lim RH2T Magazine Vol 2, Dec 2009 Stepper motors operate differently from normal DC motors, which rotate when voltage is applied to their terminals. An Overview Stepper motors were developed in the early 1960′s as a low cost alternative to position servo systems in the emerging computer …
Remote-Controlled Robot
By: Ober Choo RH2T Magazine Vol.11 Dec 2011 When I was 8 years old, my parent bought me a remote-controlled car. It was controlled through simple console with switch to activate and deactivate the motors on the car. Now, I can create my own remote-controlled robot, isn’t that fun?! You can create your …
Quadrature Encoder
By: Ling Dian Miao RH2T Magazine Vol.7 Dec2010 Rotary encoder is a sensor attached to a rotating object (such as a shaft or motor) to measure rotation. By measuring rotation your robot can do things such as determine any displacement, velocity, acceleration, or the angle of a rotating sensor. 1.0 …
How RC Servo Works?
Since many students and hobbyists are using RC servo in their projects, let’s take a look at the RC servo (servos for short). The purpose of this information is to give an overview of how servos operate and how to communicate with them.
